There decision height was 362m QNH (baro) or 100m QFE (baro). Which is 262m field elevation plus 100m decision height ABOVE FIELD ELEVATION. This is the relevant date.
The use of the radio altimeter is not permitted during a non-precision approach.
According to state regulations I am aware of there is no authorization to start an approach when the airfield is below published minima. There is nothing like a "trial" approach.
They were far below published minima.
There has been another occasion (Armavia A320 Sotchi) where a Russian ATC controller was not aware that he was not empowered to order a FOREIGN registered aircraft's pilot to go around, deny an approach approval due to weather or deny a landing clearance due to other than operational circumstances. This empowerment of ATC is valid for RUSSIAN registered aircraft only. Therefore the gorizont command and the approval for the "trial" approach is legally not relevant and the responsibility for the approach is only with the pilots, as in the Western countries. (Understanding that the "trial" approach was a NDB but not a PAR approach which would be different, of course)
Nuff said.
